Silica optical fibers modify for measurement ionizing radiation

摘要

We present the development of new methods and techniques of splicing and forming optical fibers with focusing on the development of new ionizing radiation sensors. Optical fiber-based ionizing sensors can be prepared by the combination of scintillation material and optical fibers. The type of optical fibers forming depends on the scintillation material structure. The type of scintillation material to ionizing radiation sensor preparation which can be used primary depends on the efficiency of ionizing radiation to scintillation radiation conversion. The standard types of optical fibers with different core diameters can be used for the powdered or crystalline structure of scintillation material. On the other side, the liquid scintillation material can be used in combination with microstructure fiber mainly. We prepared techniques for splicing and closing special hollow-core Photonic Crystal Fibers (PCF) and theirs cross splicing methods with standard optical fibers to using with this liquid scintillation materials. To powdered scintillation materials we prepared forming technology to optical fibers narrowing, etching etc. These techniques of fibers forming are presented.
